A 77-year-old male with hyperleukocytosis and thrombocytopenia was diagnosed with Philadelphia chromosome (Ph) -negative B-cell acute lymphoblastic leukemia (ALL) ; he was treated with induction chemotherapy. Despite an initial complete remission, hyperleukocytosis was returned 18 months later. A bone marrow smear revealed a substantial increase in the number of myeloid cells with each stage of differentiation, which was markedly different from the initial presentation, resulting in the diagnosis of Ph-negative myelodysplastic syndrome/myeloproliferative neoplasm (MDS/MPN)...

Even though leukemia is considered to be confined to one specific hematopoietic cell type, cases of acute leukemia of ambiguous lineage and patients relapsing in phenotypically altered disease suggest that a malignant state may be transferred between lineages. Because B-cell leukemia is associated with mutations in transcription factors of importance for stable preservation of lineage identity, we here investigated the potential lineage plasticity of leukemic cells. We report that primary pro-B leukemia cells from mice carrying heterozygous mutations in either or both the Pax5 and Ebf1 genes, commonly mutated in human leukemia, can be converted into T lineage leukemia cells...

Acute leukemia (AL) and myelodysplastic syndrome (MDS) are uncommon in chronic lymphocytic leukemia (CLL). We retrospectively identified 95 patients with CLL, also diagnosed with AL (n=38) or MDS (n=57), either concurrently (n=5) or subsequent (n=90) to CLL diagnosis and report their outcomes. Median number of CLL treatments prior to AL and MDS was 2 (0-9) and 1 (0-8), respectively; the most common regimen was purine analog combined with alkylating agent±CD20 monoclonal antibody. Twelve cases had no prior CLL treatment...

BCR-ABL1 negative myeloproliferative neoplasms (MPNs) are known to contain alterations of the tyrosine kinase JAK2 (located on 9p24) that result in constitutive activation of the encoded protein. JAK2 fusions are reported in acute and chronic leukemias of myeloid and lymphoid phenotypes. Here, we report an unclassified case of MPN (MPN-U) showing a t(9;22)(p24;q11), which generates a BCR-JAK2 fusion gene by fusing the BCR at intron 13 to JAK2 at intron 17 on the derivative chromosome 22. Most reported JAK2 fusions cases reveal an aggressive clinical course and long-term remissions have only been achieved after allogeneic stem cell transplantation (ASCT)...

Historically, our understanding of mechanisms underlying human leukemogenesis are inferred from genetically engineered mouse models. Relatively, few models that use primary human cells recapitulate the full leukemic transformation as assayed in xenografts and myeloid transformation is infrequent. We report a humanized experimental leukemia model where xenografts develop aggressive acute myeloid leukemia (AML) with disseminated myeloid sarcomas within 4 weeks following transplantation of cord blood transduced with vectors expressing BCR-ABL1 and a dominant-negative isoform of IKAROS, Ik6...

INTRODUCTION: Philadelphia chromosome-negative myeloproliferative neoplasms (MPNs) include polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF), and are characterized by clonal proliferation of hematopoietic cells in the bone marrow. There are numerous case reports and reviews reporting patients with coexisting MPN and plasma-cell disease such as multiple myeloma (MM) and monoclonal gammopathy of undetermined significance (MGUS). METHODS: We report 15 patients treated at our institution over a 5-year period (January 2008 to December 2012) with a diagnosis of both an MPN and MGUS or MM...

About 5% of adult B-cell acute lymphoblastic leukemias (B-ALL) are characterized by t(4;11)(q21;q23), which confers peculiar features to this B-ALL subtype, including a very immature immunophenotype and poor prognosis. We describe the case of a 21-year-old female who presented with B-ALL carrying the t(4;11)(q21;q23) and blasts positive for CD19, TdT, CD79a, CD38, HLA-DR. Before completing the Hyper-CVAD (hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone) therapy regimen, the B-cell leukemic clone still was detected, but an additional leukemic clone appeared, with morphology and immunophenotype (CD13, CD33, CD64, CD38, CD56, CD15, CD4(dim)) compatible with derivation from the myeloid/monocytic lineage...

The anomalous EVI1 rearrangements/t(3;3)(q21;q26) is more frequently found in myelocytic malignancies. 5q- syndrome is a newly defined subtype of myelodysplastic syndrome (MDS) first proposed by the World Health Organization in 2001. Cases of acute lymphocytic leukemia (ALL) with 5q- anomaly or t(3;3)/EVI1 rearrangement have rarely been reported. We report a rare 5q- syndrome case which ultimately transformed to acute lymphocytic leukemia accompanied by a secondary cytogenetic anomaly of t(3;3)(q21;q26) and EVI1 rearrangement around 3 years after the diagnosis of 5q- syndrome...

Hematogones are bone marrow precursors of B-lymphoid cells which are morphologically difficult to distinguish from blasts and/or from small lymphocytes. We report the case of a patient presenting idiopathic myelofibrosis with minimal myeloid blastic transformation causing severe pancytopenia, treated by allograft and showing in a bone marrow biopsy, a hyperplasia of B-lymphoid cells. Histopathology and immunohistochemistry identified these cells as hyperplasia of hematogones and not a transformation into lymphoblastic acute leukaemia...

The occurrence of acute bilineage leukemia is thought to be the malignant transformation of a myeloid or lymphoid leukemic progenitor with the potential to differentiate into the other lineages; however, the mechanisms of this lineage switch are not well understood. Here, we report on the extremely rare case of adult Philadelphia chromosome-positive acute bilineage leukemia, which is characterized by T-cell acute lymphoblastic leukemia and acute myelomonocytic leukemia. Chromosome analysis showed 46,XY,del(7)(p11...

Initially considered to be of natural killer (NK)-cell origin, CD4+ CD56+ blastic tumors (BTs) of skin have recently been proposed to be of dendritic cell lineage. We have previously described BTs with transformation to myelomonocytic leukemia. Here we report expression of the lymphoid proto-oncogene TCL1 in 10 (83%) of 12 BTs and in lymph node plasmacytoid dendritic cells (DC2s). TCL1 was also expressed in myelomonocytic blasts of 3 transformed BT cases but not in true NK-cell tumors (n = 18), de novo acute myelomonocytic leukemias (1 of 14, 7%), or mature T-cell malignancies (1 of 112, < 1%), with the exception of T-prolymphocytic leukemia (T-PLL)...

The t(4;11) translocation is the cytogenetic hallmark of a subset of acute lymphoblastic leukemias characterized by pro-B immunophenotype and a dismal prognosis. This translocation fuses the MLL gene on chromosome band 11q23 and the AF4 gene on 4q21, resulting in the expression of fusion transcripts from both translocated chromosomes. The MLL-AF4 chimeric transcript is thought to mediate the leukemic transformation. The MLL genomic disruption detected by Southern blot and the RT-PCR for the MLL-AF4 chimeric transcript expression are molecular evidence of this chromosomal translocation...

The adenine nucleoside analogue, fludarabine phosphate, in combination with cytosine-arabinoside (Ara-C) and granulocyte-colony stimulating factor (G-CSF) (the so called FLAG regimen) has recently been shown to be effective in the treatment of poor-prognosis acute non-lymphoid leukaemia. We used this combination plus novantrone (FLANG regimen) in a case of Ph1+ chronic myeloid leukaemia (CML) unresponsive to interferon alpha that had progressed to an acute phase, after 3 months of treatment with 6-mercaptopurine and hydroxyurea...

Trisomy 13, as a sole karyotypic abnormality in acute leukemia, has been reported in several cases. However, in chronic myelogenous leukemia (CML), only two cases with this abnormality were reported so far. We describe herein a 68-year-old case with Philadelphia chromosome-negative CML and trisomy 13. Leukocytosis was pointed out during the treatment for other diseases. After 7 months, abrupt increase in leukocyte count (108,000/microliters) and splenomegaly developed. Decreased neutrophil alkaline phosphatase activity and morphological features fulfilled the diagnostic terms for CML...

Preleukemic syndromes (PLS) evolve to acute myeloid leukemia (AML) in 15-50% of cases, but rarely transform to acute lymphoblastic leukemia (ALL). AML following preleukemic syndromes has a poor prognosis, but little is reported about the outcome of secondary ALL. From the adult leukemia database at MD Anderson Cancer Center, nine patients with ALL following myelodysplastic syndrome (MDS) (n=6), smoldering leukemia (n=1), or cytopenias with dysplastic features (n=2) were identified. Clinical and laboratory features were abstracted from the database, patient charts, review of the bone marrows and special laboratory studies...

The novel hematopoietic growth factor FLT3 ligand (FL) is the cognate ligand for the FLT3, tyrosine kinase receptor (R), also referred to as FLK-2 and STK-1. The FLT3R belongs to a family of receptor tyrosine kinases involved in hematopoiesis that also includes KIT, the receptor for SCF (stem cell factor), and FMS. the receptor for M-CSF (macrophage colony- stimulating factor). Restricted FLT3R expression was seen on human and murine hematopoietic progenitor cells. In functional assays recombinant FL stimulated the proliferation and colony formation of human hematopoietic progenitor cells, i...

Chromosome translocations that disrupt or alter gene function have been implicated in the pathogenesis of a variety of malignancies. Therefore, identification of a translocation breakpoint has become a more important means by which to identify genes involved in cellular transformation. A common site of translocation in myeloid and lymphoid malignancies involves 11q23. One human protooncogene, ETS1, has been localized to this chromosomal segment, and several tumours with 11q23 translocations have been shown to have altered ETS1 DNA migration after restriction enzyme digestion...

Agnogenic myeloid metaplasia (AMM) is a chronic myeloproliferative disorder arising from a single hematopoietic cell. Approximately 5% of reported cases of AMM have terminated in leukemic crisis; however, the precise characteristics of the leukemic cells have rarely been reported. We report a case of AMM that occurred in a 42-year-old man and was complicated by leukemic transformation. The leukemic cells were morphologically lymphoblastoid cells with a negative reaction to peroxidase staining, and phenotypically characterized as CD7+, CD34+, HLA-DR+, CD4-, CD8-, CD10-, CD13-, and CD33-...

Most cases of acute lymphoblastic leukemia (ALL) arise from malignant transformation of B-cell precursors in the bone marrow. Recent studies have shown that normal and leukemic B-cell precursors bind to bone marrow stromal cells through the beta-1 integrins VLA-4 and VLA-5, thereby exposing early lymphoid cells to regulatory cytokines. It has been recently reported that the pre-B cell line NALM-6 is capable of migrating under layers of murine stromal cells in vitro (Miyake et al. J Cell Biol 1992;119:653-662)...

Acute lymphoblastic leukemia (ALL) developing in myelofibrosis (MF) and myeloid metaplasia (MM) is reported in two patients. In both cases, the clinical course of the "blastic crisis" was rapidly progressive with little response to chemotherapy. The circulating cells were readily identified as lymphoblasts on the basis of cytology, cytochemistry, immunologic studies, and ultrastructure. In one of the cases, 40% of cells had T-cell markers and all cells contained paranuclear acid phosphatase. In the second case, cells had a "Burkitt-like appearance, contained multiple cytoplasmic vacuoles positive for oil red O, and one-third of them had B-cell markers...
